I turned the M4 up a little to high I guess, cuz when I turned it up the sound died and all lights went out (fan too). I have 120v coming in so I checked all the little fuses I could see. I did blow a fuse on one of the tubes, but everything is still dead. Is there a fuse somewhere that is somewhat hidden that would cause this? Heeeeelllp!_________________you can tuna piano but you can't tune a fish
